Abstract
Dilated cardiomyopathy (DCM) is a life-threatening disorder whose genetic basis is heterogeneous and mostly unknown. Five Arab Christian infants, aged 4-30 months from four families, were diagnosed with DCM associated with mild skin, teeth, and hair abnormalities. All passed away before age 3. A homozygous sequence variation creating a premature stop codon at PPP1R13L encoding the iASPP protein was identified in three infants and in the mother of the other two. Patients' fibroblasts and PPP1R13L-knocked down human fibroblasts presented higher expression levels of pro-inflammatory cytokine genes in response to lipopolysaccharide, as well as Ppp1r13l-knocked down murine cardiomyocytes and hearts of Ppp1r13l-deficient mice. The hypersensitivity to lipopolysaccharide was NF-κB-dependent, and its inducible binding activity to promoters of pro-inflammatory cytokine genes was elevated in patients' fibroblasts. RNA sequencing of Ppp1r13l-knocked down murine cardiomyocytes and of hearts derived from different stages of DCM development in Ppp1r13l-deficient mice revealed the crucial role of iASPP in dampening cardiac inflammatory response. Our results determined PPP1R13L as the gene underlying a novel autosomal-recessive cardio-cutaneous syndrome in humans and strongly suggest that the fatal DCM during infancy is a consequence of failure to regulate transcriptional pathways necessary for tuning cardiac threshold response to common inflammatory stressors.

Abstract
It is important for veterinary administrators to apply knowledge bases from other fields to their own unique administrative needs. For example, although some resources are written for business managers, the discussions of four key management competency areas, guidelines for mastering these skills, organizational assessment tools, and other self-help tools may provide interesting food-for-thought for veterinary administrators.(76) In developing their own administrative styles, administrators should seek to apply those principles that seem to intuitively fit with their personal research styles, work situations, managerial styles, administrative preferences, and unique organizational culture. Through strengthening their liaisons with community and university business programs, counseling agencies, employee assistance programs, and psychology researchers, administrators can continue to be exposed to and benefit from new paradigms for consideration in veterinary medical environments. Through these liaisons, the unique needs of veterinary medical environments are also communicated to individuals within the fields of psychology and business, thus stimulating new research that specifically targets veterinary medical environment leadership issues. Each field has unique contributions to help veterinary administrators work toward creating veterinary medical environments that are creative, energetic, visionary, pragmatic, and highly marketable in order to help administrators recruit and nurture the best and brightest veterinary researchers, teachers, and clinicians.
